Hi all,
Attached is a diagram of Peppy’s custom 70mm lens with dimensions on each of the components. If you do want to build a copy of this, I’m happy to clarify any of these instructions or lend advice alone the way.

Sam and I met on Friday and reassembled Peppy from it’s sad party face:

(It fell from the ceiling due to a very heavy HDMI cable after I tore out the USB port of the servo board through more incompetent ceiling mounting and things just went from bad to worse as the night wore on and I attempted solder, gorilla glue, psychobabble, …)

We took the opportunity to better-document how to build a Peppy. These are the things you need:

Peppy BOM

AAXA Technologies P300 400 Lumen HD Pico Projector
<Pasted Graphic 1.tiff>
ACHROMAT, 22MM DIA BY 70MM FOCAL LENGTH 

<Pasted Graphic.tiff>



Multipurpose 6061 Aluminum Tube
1" OD, .902" ID, .049" Wall Thickness

<Pasted Graphic 1_1.tiff>


Multipurpose 6061 Aluminum Tube 3/4" OD, .652" ID, .049" Wall Thickness, 1' Length

<Pasted Graphic 1_1.tiff>



Black Delrin ® Acetal Resin Sheet
1/2" Thick, 6" x 6"

<Pasted Graphic 2.tiff>


Parallax Servo Controller

Then, you do this:

Gently pry out the circuitboard from the enclosure; unplug speaker, fan, RGB, and DLP

Unscrew the lens and light source

Snip lens cover off of front plastic panel

Reassemble projector

…and at the end you have a peppy!

Sam’s working on a few sketches of the milled parts, and I’m thinking of posting the instructions to lowerquality.com
